“My real name is ‘Kelss,’” he said on an episode of “Bussin’ With the Boys,” causing a minor uproar with NFL fans worried we had been mispronouncing the name for a decade.

Technically speaking, that’s exactly what we had been doing (and continue to do) — because that’s how they pronounce it.

Both brothers ended up elaborating on the matter. Turns out, the proper pronunciation is “Kelss,” but Jason and Travis always have gone by “Kel-see” because of a change their father made earlier in his life.

“My dad, at some point when he was working in the steel mills in Cleveland, Ohio, got tired of correcting everybody who was calling him ‘Kel-see,’” Jason told SportsRadio 94WIP in Philadelphia. “Apparently, the correct pronunciation, the standard pronunciation is ‘Kelss.’ That’s what the rest of the family goes by. So, my dad, out of pure laziness completely changed his last name. And now, I think we’re at the point where we’re both riding with ‘Ed Kel-see.’ He’s, for some reason, decided to change it and that’s what we’ve gone by our whole lives.”
